Fifteen Vocalists in Fifteen Minutes

From a Facebook thing I got tagged with, but I'm sharing it here also. I found it interesting to see what vocalists swam to the surface of my mind when I was just staring at the sky and thinking about music.

The rules:  Don't take too long to think about it.  Fifteen vocalists that will always stick with you.  List the first fifteen you can recall in no more than fifteen minutes.  And in no particular order.  Tag fifteen friends.

1. Ella Fitzgerald
2. Annette Hanshaw
3. Billie Holliday
4. Louis Armstrong
5. Paul McCartney
6. John Lennon
7. Dean Martin
8. Frank Sinatra
9. Bob Dylan (and not in a good way ...)
10. Steve Goodman
11. John Prine (also, not really in a good way, though I find him more tolerable than Dylan)
12. Bonnie Raitt
13. John Hiatt
14. Tom Petty
15. Mark Knopfler
